a Ser/Thr phosphatase. Plays a role in the survival of cells in a low oxygen stress by suppressing a hypoxia-induced ASK-1/MKK4/JNK signaling cascade that promotes apoptosis. Has been reported to interact with DNA-PK, dephosphorylating it at two functional sites. May play a role in the regulation of RNA biogenesis and/or mitosis.
